SPRING SUSPENSION FOB. VEHICLES.

Specification of Letters Patent.

Patented Nov. 29, 1910.

Application filed January 4, 1910. Serial No. 536,396.

To all whom it may concern:

Be it known that I, PROSPER MoRRnN, a subject of the King of Belgium,residing at Brussels, Belgium, have invented certain new and usefulImprovements in Spring Suspension for Vehicles, of which the followingis a specification.

The object of my invention is to prevent or avoid not only the suddenshocks which may be caused to a vehicle by rough places on a bad road,such as hollows, and hillocks, etc., but also all vibrations produced byinequalities of the road, bad paving, etc. For this purpose, the chassisor frame of the vehicle is mounted upon springs of the kind shown in theannexed drawing, which is a view in side elevation, partly in section.

The spring is formed of two half springs R, R, adapted to a cylindricalbox A. One of the half springs is fixed at its end to the chassis of thevehicle in the ordinary manner. The free end of the other half springcarries a roller which rolls on a concave surface M N also fixed to achassis or frame. The rolling surface may be adapted to the end of thehalf spring and the roller to the chassis or frame of thevehicle.

The cylinder box A contains a spiral spring B which presses upon apiston E connected to the axle L of the wheel. This spring is held inthe hollow piston in the center of which is passed a rigid rod P guidingthe movements of the cylindrical box. This rod is provided with anexterior spiral spring I) pressing upon the box A and is for preventingthe piston E from completely leaving the box.

The action of the apparatus thus arranged will be readily understood;the inequalities or unevenness of the ground, rough paving, etc., act onthe spring B through the piston E which suppresses the vibrations, orrather prevents them from being transmitted to the frame or chassis ofthe vehicle.

Should the wheel encounter an extra bad piece of ground, a deep rut,hillock, obstacle or the like, at the same time as the piston E plungesinto the box A, compressing the spring B and thus partly destroying theeffect of the obstacle on the vehicle, but also the free end of thespring It slides over the concave surface M N and allowing the spring Rto flatten and to yield completely to the unevenness of the groundwithout subjecting the vehicle to any shock.

\Vhat I do claim as my invention, and desire to secure by Letters Patentis 1. In a suspension device for vehicles and the like, a supportingspring means fastened at one end to the vehicle frame and free at theother end, together with an inclined bearing surface rigid with thevehicle body over which said free end travels when the spring issubjected to stress, substantially as described.

2. In a suspension device for vehicles and the like, a supporting springmeans fastened at one end to the vehicle frame and free at the otherend, together with an inclined bearing surface rigid with the vehiclebody over which said free end travels when the spring is subjected tostress, together with means for cushioning said spring means upon theaxle of a wheel, substantially as described.

3. In a suspension device for vehicles and the like, a supporting springmeans fastened at one end to the vehicle frame and free at the otherend, together with a curved bearing surface rigid with the vehicle bodyover which said free end travels when the spring is subjected to stress,substantially as described.

4-. In a suspension device for vehicles and the like, a supportingspring means fastened at one end to the vehicle frame and free at theother end, together with a bearing surface curved approximately in thearc of the spring when the latter is subjected to stress, over whichbearing surface the free end of the spring may t'avel, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
